I2 4 CRUSTACEA MALACOSTRACA. III. 



spines or crenulation on the front margins of the four anterior segments; small differences in the 

 appendages may be derived from Sars' figures of both species. The shape of the proximal joints of 

 the antennce is also of some significance; their shape can be seen on fig. 7a. 



Occurrence. Captured by the "Ingolf" at four stations in the warm area, ten stations in the 

 cold area and one station with lesser depth.

 Besides, I. hirticeps has been taken at nine places in our area. From Baffin Bay and Davis 

 Strait it was recorded (by H. J. Hansen) from three localities, viz: Lat. 72°4i' N., Long. 59°5o' W., 227 

 fath.; Lat. 7i°io' N., Long. 58°56' W., 199 fath., and Lat. 66°32' N., Long. 55°34' W., 100 fath. — North 

 of Iceland it was secured by Admiral Wandel in the Skagestrand Bay, 119 fath., temp. 2-9°. The "Thor' 

 has captured it at the following five places. 



South of Iceland: Lat. 63°i5' N., Long. 22°23' W., 114— 172 fath.; many spec. 



— - Lat. 63°5' N., Long. 20°7'W., 290 fath.; 1 spec. 



— - Lat. 62°n' N., Long. i9°36' W., 1010 — 1142 fath.; 2 spec. 

 South-West of the Fseroes: Lat. 6i°i5' N., Long. 9°35' W., 463— 515 fath.; 8 spec. 



- - Lat. 6i°7' N, Long. 9°3o' W., 443 fath.; 9 spec. 



Distribution. The "Thor" captured some specimens west of most southern Norway: Lat. 

 58°32 f N., Long. 4°i8' E., 148 fath. It has been taken along the coast of Norway from Stavanger 

 Fjord to Vadso in Varauger Fjord, 100 to 400 fath. (G. O. Sars). The Norwegian North-Atlantic Ex- 

 pedition has gathered it at three stations off the coast of Norway in the cold area in depths from 

 417 to 649 fath.; furthermore north-east of the Fteroes in 1215 fath., temp, -r- i"2°; between Norway and 

 Beeren Eiland, 191 fath., temp. 3-5°; west of Beeren Eiland, 658 fath., temp, -f- 1-2°; finally at three 

 stations near Spitzbergen, one with 1333 fath. and temp. -=- 1-4°, another only 146 fath. and temp. ri°, 

 while the third, with 260 fath., lies even so far northwards as in Lat. 8o°3' N. Ohlin also recorded it 

 from Spitzbergen; two of his stations are off King Charles Island, one of them even so far eastward 

 as Long. 29°39' E., and the depths of only 32—37 fath. and 10 fath.
